Base and compressed difference data deduplication

A method, comprising:

• processing a write Input/Output (I/O) request to a memory to extract data of the write I/O request;
• accessing a table to identify a first portion of the data of the write I/O request that is stored at a first address of the memory;
• assigning a pointer to the first portion of the data in the table;
• identifying a second portion of the data of the write I/O request that is not stored in memory;
• and
• writing the second portion of the data of the write I/O request to a second address of the memory.

A non-transitory computer readable medium comprising instructions that, when executed by an Input/Output (I/O) module, direct the I/O module to:

• process a write I/O request to a memory to extract data of the write I/O request;
• access a table to identify a first portion of the data of the write I/O request that is stored at a first address of the memory;
• assign a pointer to the first portion of the data in the table;
• identify a second portion of the data of the write I/O request that is not stored in memory;
• and
• write the second portion of the data of the write I/O request to a second address of the memory.
